生物活性

YYSW001 is a selective and orally acrive JAK1 inhibitor with an IC50 of 6 nM and a Kd of 32.32 μM. YYSW001 blocks JAK1-dependent phosphorylation of STAT6, as well as IL-6-induced phosphorylation of STAT3. YYSW001 suppresses pro-inflammatory cytokine levels, reduces paw swelling, lowers clinical arthritis scores, alleviates joint damage and decreases bone loss. YYSW001 is applicable for the research of rheumatoid arthritis[1].

体外研究
(In Vitro)

YYSW001 (2 h) 可强效抑制 THP-1 细胞中 JAK1 依赖的 STAT6 通路 (IC50 = 0.041 μM),对 TF-1 细胞中 JAK2 依赖的 STAT5 通路仅表现出弱抑制作用 (IC50 = 5.530 μM)[1]
YYSW001 (72 h) 可强效抑制 Ba/F3-TEL-JAK1 细胞的增殖 (IC50 = 290.2 nM),而对 Ba/F3-TEL-JAK2、Ba/F3-TEL-JAK3 和 Ba/F3-TEL-TYK2 细胞的活性极低[1]
YYSW001 (15 min) 可抑制人全血细胞中 IL-6 诱导的 JAK1 依赖型 STAT3 磷酸化 (IC50 = 7065.0 nM in CD3+ T cells, 3001.0 nM in CD14+ monocytes),且对 GM-CSF 诱导的 JAK2 依赖型 STAT5 磷酸化的抑制作用极弱[1]
YYSW001 具有良好的体外 ADME 特性,包括优良的肝微粒体稳定性与血浆稳定性、极低的 CYP3A4 和 hERG 抑制活性、中等通透性以及中等血浆蛋白结合率[1]

Cell Viability Assay[1]

Cell Line: Ba/F3-engineered cell lines (Ba/F3-TEL-JAK1, Ba/F3-TEL-JAK2, Ba/F3-TEL-JAK3, Ba/F3-TEL-TYK2)
Concentration: serial 2- or 3-fold dilutions (nine gradients)
Incubation Time: 72 h
Result: Exhibited potent inhibitory activity against Ba/F3-TEL-JAK1 cells with an IC50 of 290.2 nM.
Showed negligible inhibition against Ba/F3-TEL-JAK2, Ba/F3-TEL-JAK3, and Ba/F3-TEL-TYK2 cells (IC50 > 10000.0 nM for all three cell lines).
Achieved a cellular JAK1/JAK2 selectivity ratio of 38.6.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
